Just a last comment: I've no idea if the bug might be exploitable. I
haven't had a deeper look at what it fixes but in regard to memory
problems I would prefer a careful solution. So even without fixing the
problem of an undefined return code in case of an oom (and the imho more
problematic ugly output of a (with gcc 4.9 colored) warning when
compiling the kernel, it might be better to apply the patch.

Regards,

Alexander Holler
